List all cohorts in the project. Returns cohort IDs, names, and metadata.
AI agents call list_cohorts to retrieve information from Mixpanel MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns existing cohort metadata without modifying, creating, or deleting data. It is purely informational, consistent with other Read category tools on this server (list_annotations, query_events, etc.). The blast radius is minimal since listing cohorts does not trigger external operations or expose sensitive PII—only project-level cohort metadata.
From the tool's definition Tool name 'list_cohorts' and description 'List all cohorts in the project. Returns cohort IDs, names, and metadata' indicate a retrieval/query operation with no side effects.
Attacks that exploit this kind of access
List all cohorts in the project. Returns cohort IDs, names, and metadata. It is categorised as a Read tool in the Mixpanel MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Mixpanel MCP Server MCP server in PolicyLayer and add a rule for list_cohorts: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mixpanel MCP Server. Nothing to install.
list_cohorts is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_cohorts rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_cohorts. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_cohorts is provided by the Mixpanel MCP Server MCP server (t-campbell18/mcp-mixpanel). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
